JOURNAL-BOX JACK.

Specification of Letters Patent.

Patented July 26', 1921.

Application filed March 1, 1918. Serial No. 219,897.

T 0 all whom it may concern Be it known that I, GUY WV. RUTLEDGE, a citizen of the United States, residin at Huron, in the county of Beadle and tate of South Dakota, have invented certain new and useful Improvements in J ournal-Box Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to.which it appertains to make and use the same.

This invention relates to car jacks and the primary object of the invention is the provision of an improved jack for lifting journal boxes, so that the brasses can be readily removed and inserted into the same.

Another object of the invention is the provision of an improved car jack having means for engaging the upper surface of the car wheel, a jack depending from said means, and flexible means depending from the box so that upon operation of the jack, the journal box will be lifted upwardly and the weight thereof sustained by the car wheel, so that the brassings or bearings can be readily removed or inserted from the journal box.

A further object of the invention is to provide an improved suspension car jack including a supporting member carrying the jack which can be either suspended from the car wheel to lift the journal box upwardly or can be inverted and set upon a platform supported by the car rails for pushing the journal box upward.

A still further object of the invention is A to provide an improved journal box jack of the above character which is durable and efficient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a reasonable cost.

. With these and otherobjects in view the invention consists in thenovel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part thereof, in which Figure 1 is a front elevation of a car wheel showing my improved jack applied thereto, showlng the journal box in section.

Fig. 2 is a side elevation of'the car wheel showing my improved jack applied thereto with parts of the same in section. v

jack for engagement with the journal,

Fig. 3 is a view of the improved jack showlng the same supported upon a platform, which is adapted to be placed on the railroad rail, and

Fig. 4 is a plan view of the platform for receiving the car jack.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indi-.

cates the improved jack which is adapted to lift a journal box 2 of a car wheel 3 for removing or inserting the brass 4 therefrom. p 7

The improved jack 1 includes a supporting bracket 5, which is adapted to engage and be supported by the car wheel 3, and the same has its under surface at the rear end thereof provided with a transversely extending groove 6 for receiving the flange 7 of the car wheel 3 and for forming a hooked end for engaging the inner side of the wheel. A ment8 is formed on the outer end with a bracket 5 in spaced relation to the hooked end thereof and forms a shoulder 9, which is adapted to engage the outer sideof the car wheel 3. The enlargement 8 bearing against the outer side of the car wheel prevents the bracket from sagging, when the journal box 2 is being lifted. A vertical aperture 10 extends through the bracket 5 and the on largement 8 in which is positioned the lifting screw 11 and the same is supported by and operated by a nut 12, which is positioned in the inwardly extending slot 13, which communicates with the aperture 10. The lower end of the lifting screw -11 is provided with a head 14, the purpose of which willbe hereinafter more fully described. The upper surface of the bracket 5 is provided with a smoothbearing portion 15, the purpose of which will hereinafter more fully appear. Positioned above the head 14: of the lifting screw 11 and on each side thereof is a hook 16 for receiving the free ends of the flexible chain 17, which is adapted to extend around the journal box. In operation of the improved device, the bracket 5 is placed on top of the car wheel 3 so that the inner end of the same is hooked over the wheel and the flange 7 of the car wheel is placed in the transverse groove 6 and the flexible chain 17 is then positioned around the journal box 2 and its ends are hooked over the hooks 16, Upon rotation downwardly extending enlargeof the operating nut 12, the lifting screw will be forced upwardly carrying the journal box 2 therewith, which will permit easy removal or insertion of the brasses & from the journal box.

In some few instances it has been found by practical experience that the suspension bracket 5 cannot be laced over the vwheel- 3 owing to the fact that the frame of the car is too near the car wheel due! to breakage of the body and -to provide for this occurrence a hat plate- .or platformv 18 is provided for supporting the jack. The platform consists of a bodylE) having inwardly extending spaced arms. 20 formed on the, end thereof between which is adapted to be, positioned the car wheelr3 and the arms have their inner'surfaces thereof adjacent to their outer ends. provided with grooves 211 for receiving: the flange/7 on the can wheel. centrally disposed; in-, wardly extending tongue 22: is formed, on the body intermediate the arms 20 and is arranged to engage; the inner surface of the tread of the wheel; to;preventdisplacement of the plate. This plate ijs-positionedon the track with the arms on; each side of: thewheel as described above, and the plain outer-surface 15} of the bracket 5is placed upon the bodyportion-19 of the platform which projects, outwardly fromthe: wheel andv track and is, positioned below the journal box 2. The chain: l-Tis unhooked: from the hook 16 and'the nut 12-: rotated for bringing, the head 14 under the journal box and: upon;

mit the removalof the. brasses ttherei from.

From the foregoing description taken in connection with the drawings. it can. be

' seen that an improved and simple journalbox jack, is. provided f urther'rotation of the nut 12' the-journalbox will be lifted so as to per-- in practice,l have found that the form of my invention, illustrated in the acconi panying drawings andreferred to in theabove description, as the preferred embodiment, is the most efficient and practical; yet

realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of partsrmay be resorted to, when required without sacrificing any of advantages of my invention asset forth.v v v 1 What I claim as-new is I 1. A journal; box :jack comprising a bracket, a1 lifting member adjustably mounted in the bracket andopera-bly and selectively extensible beyond opposite faces thereof, saidbracket being reversible and one of the said faces being engageable with a car wheel; and. the. other face; being .engageable with'a support auxiliary to the car wheel. '1' 1 o 1 "2. A journal box jack comprising a bracket provided. with aninwardly extendingrslot at one end, alifting screw member mounted in said. end and crossing the slot, a nuton the screw member in the slot operable to selectively extend the: screw member beyond the upper or the bracket, said bracket being reversible with its lower surface provided) with acar wheel-engaging portionand with its upper surface substantially flatin order to rest ona support auxiliary'tothe car wheel."

3;" Asupport for journal box jacks comallel arms extending therefrom and a space intermediate the arms, a fl'at whe'elengag ingprojection extending into the space and lyingin the same plane as the body, and said-arms at their inner edge having a notchextending completely"therethrough.

lin testimony whereof'l aflix my signature in presence of two witnesses." 9 g V 'G'UY WV; RUTLEDGE.
